2 Claims. (o1. 268L126) P This invention relates to 'afwindow regulator I and more particularlyito a mechanism for raising' and lowering window panels for automobile bodies.

It is an object of the present invention to provide an improved window regulator of theabove type having a. pair of swinging arms in the shape ofbell cranks,the outer free .ends of'thearms "being slidinglyconnected to the channel bar at the. lower'edge' ofethe window glass; to interconnect the bell cranks by a link; and to produce equal movement .in opposite swinging directions of the outer ends of the arms by a pivotal, swinging link connection to one of the bell crank arms.

Another objectorthe-invention i -to arrange the pivotal point of the arms on .a plate member insuch a manner that a limited amount of movement is required for a maximum lift so that the assembly requires very little room, in the win--' dow well.

A further object of the invention is to arrange the swinging arms in crossed relation so that one arm swings past the pivotal point of the other arm and the other arm swings past the pivotal point of the first arm.

Other objects and advantages of the invention will more fully appear from 'the followingdescription taken in connection with the accompanying drawings in which:

Fig. 1 is an inside fragmentary side elevational view of an automobile door partly broken away, illustrating a window regulator in which the present invention is embodied;

Fig. 2 is an enlarged side face view of the mechanism with the inner door panel, to which the mechanism is applied, removed; 7 h

Fig. 3 is a top plan viewof Fig. 2, showing the mechanism attached to the inner panel of the door; V

Fig. 4 is a view corresponding to Fig. 2, but showing the regulator arms in a position for partially lowering the window glass; and

Fig. 5 is a top plan view of Fig. 4.

The present invention relates generally to window regulators especially applicable to the window well of an automobile door or between inner extend into thelwell to support the win- 'dow 16 when it is lowered and concealed from view *by'the door panels.

The window 16 has secured to its lower edge the usual channel bar 20 provided with a pair: of horizontally extending slots 22 and 24 for receiving studs orrollers Z'Iiand 28 carriedby the free ends of the lifting arms 30 and 32 of the reg- 3 ulator mechanism. g

"The complete I regulator mechanism comprises twqmechanical assemblies, one a-power input mechanism; designated as A, and fully disclosed in my 'copending application, Serial No. 270,489, filed February .7, 1952, and the other, designated as B tfor ming my'improved lowering and raising mechanism whicl'l' forms the subject matter of the present invention. The two assemblies may be usedin conjunction with each other, or other powerl input means may be usedto operate my mproved lowering and raising mechanism.

The improved assembly B includes a plate 34 having a centrally depressed portion 36 which is attached to the inner panel 12 by screws or rivets 38, and ofiset opposite end portions 40 and 42 spaced awayjfrom the inner panel l2.

arms 30 and 32 at 44 and 46. counterbalance torsion springs 41, surrounding the pivots 44 and 46, have their free ends connected to the plate 34 and the arms 30 and 32.

The lifting arm 30 is pivoted at 46 and has a short arm 48 extending radially from the pivot 46 and at an acute angle to the radial line of the arm 30. The free end of the arm 30, in its raised position, extends upwardly and in a direction on the side of the end portion 40 of the plate 34. In the swinging movement of the arm 30 it will pass the pivot 44. v

The lifting arm 32 is pivoted at 44 and extends upwardly in a curved path from the pivot 44 toward the side of the end portion 42 of the plate 34. The arm 32 has a short arm 50 extending radially from the pivot 44 and at an acute angle 7 to the arm 32. The short arm '48 extends generally in an upward direction and the short arm 50 extends generally in a downward direction. A pivot 52 is carried by an ofiset portion 54 andis integral with the arm 32 and the short arm 50.

This pivot 52 lies between the arm 32 and the short arm 50. A link 56 is pivotally connected at its opposite ends to the pivot 52 and the pivot 58 at the free end of the short arm 48.

The offset end portions pivotally support the lifting tion below the pivots 44 and 46 when in their lowered position; that is, the one arm swings past the pivot point of the other arm. By this cross arrangement of lifting arms, I have been able to provide long lifting arms for a maximum swinging movement in a comparatively short space.

The arms 39' and 32 are connected together by the link 56 and any movement of onewill impart movement. to theother. The power input is applied to the arms 30 and 3-2 through 'aniactuatin'g bar '60, shown here as pivotally connected at 66 to the short arm 50 and at its opposite end to the. crank mechanism A which may be remotely located from the lifting mechanism B.

The studs 26 and 28 are received. intheslots :27. and 24 of the glass channel bar 2.0, and. the raising or lowering power as applied through a push mechanism, an actuating bar connecting said actuating mechanism for imparting movement from said actuating mechanism to said lifting mechanism, said lifting mechanism including a supporting plate, a pair of bell crank levers each having a relatively long free end portion and a relatively short angular end portion, the long free end portions being adapted for window movement engagement, said arms being pivotally connected to said supportingplate-wand arranged in cross relation for movement of each arm past the pivotal connection of said other arm, and a link interconnecting the short end portions of said comprising, a supporting plate having ofiset end or pull action of the actuating'-bar'fifi,'willcause I the arms 3!) and 32 to swing, moving the "window glass in its glass run channels 18. Since the long arms 30. and. 32 are of equal. length, .andthe short arms 50 and 48 are. of equal length, the power applied to the channel bar Zflis equalat its opposite sides and raisingorlowering movementis the same, .so that there isno danger inbindingp'f the glass.(

The regulator is constructed for efficient operation. and inexpensive manufacture. It can be manufactured from sheet metal stampingsand readily assembled preparatory to application asa unit to thevehicle body.

It will be understood that various changes including the size, shape, and arrangement ofparts may'be made without departing from the spirit of my invention and-it is notr my intention to limit its scopeother than by the terms of the appended claims. v
